I don't see why everyone complains about killing off their fireflies with unstable gas when upgraded. Just wait until the opponent has low enough health!
So what is the sense to wait, when FF+EpiDamsefly can deal the same damage and You don't need waste 5
and one turn for UG
Of course sometimes UG is useful, but when we talk about FFQ then UG didn't work good and gives more problems (kill all field) than advantage, especially when You should use SkyBlitz which is faster and better here.
Concept
for unupped and
for upped FF is much better and more reasonable than situation which we have today. I think that it will be also good decision turning 4|2 for
FF into 3|4 (can alive 2 UG more) and increasing stats for
FF into 4|2. Then it is more balanced...
Unupped FF - 3|4 - generate
Upped FF - 4|2 - generate
(or maybe
)
Don't You think that it is better?
